IMPROVEMENT IN PAPER-FILES.

Speciiication forming part of Letters Patent No. 119,917, dated October17, 1871 antedated September 27, 1871.

To all whom it may concern:

Be it known that I, CASS CHAPMAN, of the city of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Pigeon-Holes.

My invention has for its object to produce a frame or skeleton for thereception of boxes or drawers without the use of bolts, nails, orscrews, which shall be perfectly portable and easy of transportation,and can be readily taken apart and put together again, Ste.; andconsists in forming the same of thin sheet metal so cut and bent up thatthe parts are easilyinterlocked, and when so interlocked form a perfect,strong frame, as will be hereinafter more fully set forth.

To enable those skilled to make and use my invention I will proceed todescribe the same reference being had to the accompanying drawingforming part of this specification, and in which- Figure l is a verticallongitudinal section at line a' a', 2. Fig. 2 is a verticalcross-section at line y y, Fig. 1, looking toward front, and Fig. 3 isside View, partial. Fig. 4 shows the parts detached.

Similar letters of reference indicate like parts in the several iigures.

A A represent the front and back of the frame; and B B, Ste., thedivision-plates or drawer-supports. These plates B are cut from sheetmetal, of the proper length, and a little wider and longer than thebottom of the drawer. The excess in the width is turned up at rightangles equally on both sides, as seen at 1, which forms side guides forthe drawer after it has been inserted. The ends are turned down equallyat right angles, the rear end passing through a slot cut for thatpurpose in the back of the frame Af; or they maybe passed throughstraight and turned down afterward, as seen at 2. The front end dropsinto its seat formed by the turn-up 3 at the mouth or opening in thefront plate. This mouth or opening is made by cutting a holecorresponding to the shape and of less dimensions than the front of thedrawer, and increased to proper size to allow the entrance thereof byturning inthe surface metal, as seen, except at the bottom, which isolea-n cut. The top is turned up, as seen at 3, forming the sea-t forthe front turn-down end of the drawer-support, and the sides 4 turned inat right angles to correspond with the plane of the guides 1 formed bythe turned-up sides of the plates B, thus forming a perfect guide on allsides for the sliding drawer C, which is made of about the design seenin the drawing, and provided with a suitable knob, D.

It will thus be seen that a cheap, neat, and substantial set ofpigeon-holes is produced, which are proof against dust, vermin, and nre,and, be

ing perfectly portable and easy of transportation,

are very desirable.
